STEM-WINDING WATCH.

SIPECIFICATION forming' part of Letters Patent No. 708,98 5, datedSeptember 1,6, 1902. Application filed May 12, 1902. Serial No. 106,871.KNO model.)

To all whom, t may concern:

Be it known that I, MORRIS BASSOFF, a citizen of the United States,residing at Brook- I Vn, in the county of Kings and State of New York,have invented certain new and usefulImprovementsinVVatchlVindingMechanism, of which the following is a fulland complete specification, such as will enable those skilled in the artto which it appertains to make and use the same.

The object of this invention is to provide improved devices for windingand setting a watch, a further object being to provide devices of thisclass which will be simple in construction and operation and which willnot easily get out of order or frequen tl y need repairs; and with theseand other objects in view the invention consists in devices for windingand setting a watch constructed and operating as hereinafter describedand claimed.

The invention is fully disclosed in the following specifieation, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, in which- Figure l is an outside view of one of theside plates of the frame of the watchwork mechanism and showing theparts of my improvement connected therewith. Fig. 2 is an inside View ofsaid plate and showing the parts of my improvement connected therewith.Fig. 3 is a section on the line 3 3 of Figs. 1 and 2; Fig. 4L, a sectionon the line 4. 4 of Figs. l and 2; and Fig. 5, a section on the line 5 5of Fig. 2, Figs. 3, 4, and 5 being on an enlarged scale.

In the drawings forming part ofthis speci- Iication I have shown theside plates of the frame of the mechanism of a watch together withcertain parts of said mechanism hereinafter described, and the sideplates of the frame are designated by the reference characters d and d2and may be connected in any desired manner. Mounted between the sideplates c and d2 is a shaft as, which carries the usual spring-barrel di,which is provided with the usual gear-wheel d5, and I also provide witha center arbor Z), which is mounted between said plate and provided witha gearwheel h2, rigidly secured thereto and which in practice operatesthe watchwork mechanism, which is not shown and which is provided with apinion 2b, in connection with which the gear-wheel d5 operates. Thecenter arbor h is provided outside of the plate a with a pinion b3, andsaid shaft also carries in practice the minute-hand of the watch, whichis not shown, and the pinion b3 operates in connection with a gear-wheelh4,mount ed on a shaft b5. In one side of the frame and between theplates a and a2 is placed a transverse plate c. Within said plate c orat the inside thereof is placed a gear-wheel c2, provided with a hub c3,which passes through the plate c and is revoluble in said plate c, andthe hub c3 is adapted to receive the shank c4 of the pendant-stein ci",and the end of the shank c!l which passes into the end of the hub c3 isangular in cross-section, and said shank passes through said hub andthrough the wheel and is movable therethrough. Inside of the wheel c2 isplaced a plated, provided at one side with pivotal projections cl2,which pass through corresponding openings d3 in the plates a and a2, andthe plate d ranges parallel with the plate c and wheel c2 and is adaptedto be turned on its pivotal support through the shank c4 of thependant-stem c5 when said shank is inserted into position, as shown.

Pivoted to the plate a at c is a yoke e2, which ranges radially of saidplate a, and the inner end of which is narrower than the outer end, saidyoke being substantially triangular in form, and the pivotal point e isnear the corner thereof formed by the base side and wider end thereof,and the opposite corner of said yoke is provided with a nger e3, againstwhich the plate d is adapted to bear, and said plate CZ forms an arm foroperating the yoke e2, in which operation it bears on the finger e3 ofsaid arm. The inner end of the yoke c2 is provided with an annularportion e4, which fits in a slot or opening f in the plate a, andconnected with said annular portion e4 of the yoke e2 is a pinion f2,which is outside of the plate c and which is adapted to operate inconnection with the large gear-wheel g on the shaft d3 of the barrel CL4and also in connection with the gear-wheel b4. The plate a, is

also provided with a slot h, through which the peri meter of the wheelc2 passes, as clearly shown in the drawings, and this slot, o1' ratherIOO the passing of said wheel therethrough, prevents the movement ofsaid Wheel toward or from the plate c and holds said wheel c2 in properposition for use, and in I of the drawings I have shown at t' aspring-operated ratchet adapted to engage the wheel g and prevent theunwinding of the barrel a4 in the operation of winding the watch.

The support of the yoke e2 at e consists of a screw or pin passingthrough the plate d, and mounted in this screw or pin, outside of saidplate, is a large gear-Wheelj, in connection with which the gear-wheelc2 operates, and Ithe gear-vvheelyl also operates in connection with thepinion f2, which is carried by the arm e2.

In the normal position of the parts the pinion is in engagement with thewheel g, and the Watch may be wound by simply turning the pendant-steinc5; but when it is desired to set the watch the key c5 is forcedinwardly. This operation presses the plate d or the yoke thereof againstthe linger e3 of the arm e2 and throws the pinion into engagement withthe wheel b4, and then by turning the key the watch may be set, as willbe readily understood, the pinion b3 being connected with the shaft l),which carries the minute-hand of the watch, as hereinbefore described,and with which in practice the hourhand is also connected in the usualmanner.

This winding and setting mechanism for watches is comparatively simplein construction and also comparatively inexpensive and is positive inoperation and is not liable to get out of order or frequently needrepairs, and changes in and modifications of the construction describedmay be made without departing from the spirit of my invention orsacriticing its advantages.

I-Iaving th us fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

I. In a Watch winding and setting mechanism a barrelshaft provided witha gearwheel, a center arbor provided with a pinion, a gear-wheeloperating in connection with said pinion, a yoke provided with a pinionnormally in engagement with the gear-wheel on the barrel-shaft andadapted to be thrown into engagement with the gear-wheel which operatesin connection with the pinion on the center arbor, a stationary plate, awheel mounted on the inner side ot' said plate and provided with. a hubwhich passes therethrough and is adapted to receive a pendantstemlongitudinally movable therein, and a plate pivoted between said wheeland said yoke and adapted to be operated by the pendant-stem, saidlast-named plate being adapted to operate said yoke, substantially asshown and described.
